Introduction

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.

Challenges

Electric motors are expensive and difficult to manufacture, and not universally available. Most thermoplastics operate at low melting points not suitable for intense or prolonged motor operation.

Approaches

3D print an electric motor using recycled plastics selected specially for high durability and heat resistance, 3D printers, and vitamins. Design with investment casting, and direct metal printing in mind.
